Definitions
- the present invention relates to a device for limitation of the steam released from a washing machine.
- the object of the present invention is that of providing a device for limiting the steam released from a washing machine, which is particularly simple and with a restricted effect on the overall cost of the machine.
- this object is achieved with a device characterised in that it is composed of a sequence of adjacent vertical chambers, separated by parallel vertical baffles alternately interrupted at the upper or lower ends for alternate reciprocal communication between the adjacent chambers and provided with intermediate deflecting walls for the partial conversion of the steam into condensation water, said adjacent chambers defining a labyrinth path with sequential chambers with an alternately rising and descending vertical flow of steam from a steam inlet aperture communicating with the washing drum of the machine to an expansion chamber provided with an upper steam outlet hole and a lower hole wherein condensation water is conveyed for return into the drum.
- the steam limitation device as a simple constructional extension of the single-block body which already forms part of many washing machines and dishwashers and combines the known functions of air break and container of regeneration water for the washing water decalcifying resins, as well as that of collection and disposal of the steam produced in the washing drum and entering through an appropriate inlet hole.
- a usual single-block body of the aforementioned type is laterally flanked by and welded to an additional body made in accordance with the present invention and communicating with the first via a window formed for this purpose in a side wall of the single-block body and forming the inlet aperture of the steam limitation device.
- Suitable means are also provided to prevent the direct flow of steam towards the usual aperture for disposal of the steam via the single-block body.
- the baffles for separation of the adjacent chambers and the deflecting walls provided in the chambers themselves are even half made in one piece with the single-block body and the other half in one piece with the additional body.
- the drawings show a working assembly which performs the functions of air break, regeneration water container and steam limitation device according to the invention.
- the first two functions are performed by a first part of said working assembly, which consists of a single-block body 1 of a box-shaped type, made in a plastic material, which is equipped with an air break device 2 and a container 3 for regeneration water fed by the air break device, for example of the type illustrated in the prior Italian utility model application no. MI94U000285 filed on 19 April 1994 in the name of the same Applicant.
- 4 in Fig. 1 denotes an inlet for clean water coming from a conventional feed solenoid valve (not shown)
- 5 denotes an outlet for the clean water which has passed beyond the air break device
- 6 denotes an outlet for the regeneration water, intended for a suitable decalcifying resin device (also not shown).
- transverse walls 7, 8 and 9 separate the aforementioned regeneration water container from an area 10 for disposal of the washing steam, which receives the steam from a steam inlet 11, in turn communicating with the interior of the washing drum of a washing machine, via a narrow passage 12 defined between walls 8 and 9 (Fig. 1), and conveys it towards an upper outlet aperture 13, partially converting it into condensation water through the impact with oblique transverse deflectors 14.
- the additional body 15 is provided with internally projecting transverse half-walls 16a which, by coupling with corresponding complementary half-walls 16b, projecting laterally from the single-block body 1, form a plurality of vertical separator baffles 16 between laterally adjacent vertical chambers 17 of a sequence of chambers, alternately communicating at the top and at the bottom, which define a labyrinth path with sequential chambers (17) with an alternately rising and descending vertical flow of steam.
- the steam which enters through the inlet 11 of Fig. 1, in fact passes (arrows F) from the single-block body 1 to the space formed between the two bodies 1 and 15 through a communication window 18 and then, after a section of horizontal rectilinear path 19 with small oblique deflecting walls 20 (half formed in turn as external projections of the body 1 and half as internal projections of the body 15), reaches the labyrinth path formed by the chambers 17, in turn provided with oblique deflecting walls 21, vertically staggered one in relation to the other but with internal edges substantially on the same vertical axis V (Fig. 2), obtained by juxtaposing internal projections of the body 15 on external complementary projections of the body 1.
- the aforementioned deflecting walls have the task of converting most of the steam in transit into condensation water, which is collected by the back wall 22 of the labyrinth path and conveyed by the same (appropriately tilted as shown in Fig. 2) towards a small transverse hole 23, which causes it to return into the steam inlet 11 and from here into the washing drum.
- the vertical baffles 16 are all slightly distanced from the back wall 22.
- the deflecting walls 21 of the descending steam flow chambers 17 have in turn their external edges slightly distanced from the adjacent vertical walls to prevent stagnation of condensation and instead encourage outflow thereof towards the back wall 22.
- the labyrinth path defined by the sequence of adjacent chambers 17 ends with an expansion chamber 24, where the small condensation return hole 23 is formed and which communicates via a final vertical path section 25 with an outlet hole 26 for the residual steam.
- a similar flooding is foreseen below the small hole 23 whose diameter is chosen as fairly small in order to prevent infiltrations of dirty water from the washing drum.
